Would all european countries look and be in the same situation like Greece or even worse if africa would stop supplying natural resources to europe ?

First, African isn’t supplying resources to Europe, any more than a rape victim is “supplying” sexual services to a rapist.  African is being robbed of its resources by Europeans and Asians with the aid of the treasonous African Elites.

If you wanna know what Europe looks like when it’s cut off from African’s resources, just review the history of the (European) Dark Ages.
